- hook up an empty uvm_pagerops like radeon does.
- hook up nouveau_ttm_mmap_object().
nouveau_engine_fifo_nve0.c:
- if (cold), don't try to wait, but hard-spin until the timeout period.
with these in place, i am able to get working text-console with nouveau!
ok riastradh.
They reject zero input, and yield zero-based indexing, unlike our
ffs/ffs64, which return zero for zero and yield one-based indexing.
May let nouveau make a little more progress toward booting!

without updating its p_waited value or its parent's p_nstopchild
counter. Later, we restore the original state, again without any
adjustment of the related values. This leaves a relatively short
window when the values are inconsistent and could interfere with the
proper operation of sys_wait() for the parent (if it manages to be
scheduled; it's not totally clear what, if anything, prevents
scheduling/execution of the parent).
If during this window, any of the checks being made result in an
error, we call exit1() which will eventually migrate the process's
state to SDEAD (with an intermediate transition to SDYING). At
this point the other variables get updated, and we finally restore
a consistent state.
This change updates the p_waited and parent's p_nstopchild at each
step to eliminate any windows during which the values could lead to
incorrect decisions.

Pullups will be requested for NetBSD-7, -6, -6-0, and -6-1
value, and update its parent's p_nstopchild value when marking the
process's p_stat to SSTOP. The process needed to be SACTIVE to get
here, so this transition represents an additional process for which
the parent needs to wait.

of reaping the process (nor any other children), the process wil get
reparented to init. Since the state of the exiting process at this point
is SDEAD, proc_reparent() will not update either the old or new parent's
p_nstopchild counters.
This change causes both old and new parents to be properly updated.

all processes to the SSTOP state. Make sure we update each process's
p_waited and the parents' p_nstopchild counters to maintain consistent
values. Should not make any real difference this late in the shutdown
process, but we should still be consistent just in case.

moved to SSTOP state, not for its parent. (It is correct to update
the parent's p_nstopchild count.) If the value is not already zero,
it could prevent its parent from waiting for the process.

eg. exists() does stat(2).
If 'wantit' is FALSE, we are going to discard everything anyway,
so skip evaluating the conditional and expanding either lhs or rhs.
add and remove loops. now when you add a new swap file and run
"swapctl -A" it won't give up after the existing one gives EBUSY
and move on to the rest.
Do not pass a SUN4U define, as that is no longer used in the relevant headers.
Instead tell the compiler we are compiling for a v9 CPU (so it internally
defines everything we need).
